Lime rotary kiln's application:
Lime rotary kiln is the key equipment for the lime production process in the building materials,its main role is calcining raw materials with high calcium carbonate,such as limestone,dolomite,chalk,shells and other materials,to produce lime.

 

Lime rotary kiln's working principle:
Lime rotary kiln's structure is advanced,low pressure vertical preheater can effectively improve the preheating effect,after preheated,lime stone enter into the kiln and is calcined in the optimum temperature of 900 ~ 1100 degree,the decomposition rate can reach 20-25%,the efficiency is higher;the sealing system on the both sides can make the rotary kiln air leakage coefficient less 10%,thus can reduce effectively heat loss;the cooler on the rotary kiln's discharging mouth can control the lime temperature in 800 degree,in order to transport and storage.
Lime stone in the preheater can be heated to 900 degree by high temperature kilns flue gas,and about 30% is decomposed,the hydraulic rod push them into the cooler.In the cooler,active lime is cooled to below 100 degree by the cool air,In the actual situation,in order to reach this temperature,in the premise of not affecting the kiln head roasting process,control the air amount of the cooler and wind pressure to ensure the effect.
